PHOTOGRAPHlC-PLATE RACK..

SPECIFICATION forming part of Letters Patent No. 662,167, dated November 20, 1900.

Application tiled June 22, l900 To cal/f whom t may con/007%:

Be it known that we, SAMUEL T. ORIssY, of Hackensack, in the county of Bergen, and WILLIAM DULLEs, J r., of the city of Englewood, State of New Jersey, have invented certain new and useful Improvements in Racks forPhotographic Washing and Fixing Baths, of which the following is a full, clear, and exact description, reference being had to the drawings which accompany and form a part thereof.

Our invention is designed to provide an improved rack or support for washing-tanks for photographic-negative plates so constructed and arranged as to receive plates of any of the sizes in common use.

It further contemplates an arrangement which will facilitate the insertion and withdrawal ofthe plateswithout danger of injury by contact with the supporting structure.

In the drawings, Figure l is a side view, partly broken away, of a tank provided with our improved rack. Fig. 2 shows the rack detached. Fig. 3 is a section upon the lines 3 3 of Fig. l.

l is a tank, preferably of rectangular crosssect-ion, made of glass or similar material.

2 is a Water-supply pipe, of rubber, which enters the tank l through a hole 3, bored, preferably, at or near the bottom of the latter. By making the hole 3 of slightly smaller diameter than the outside diameter of the rubber tube 2 a tight joint is maintained without the use of washers, packing, rbc. Near the top of the tank l one or more overiiow-holes 4 may be bored through the walls. The pipe 2 may be provided with a funnel 5, into which the Water which is to circulate in the bath is poured. By this means a suiiicient current of water may be secured in the bath to Wash thoroughly the photographic plates, the direction of iiow being from the bottom of the tank upward.

In the tank is placed a rack (i. In forming this we employ a pair of wires 7 S, preferably fixed at right angles to each other. One ,of said wires, as 7, follows the contour of a horizontal section of the tank, and the other, 8, that of a vertical section. Upon the Serial No. 21,159. (No model.)

horizontal wire 7 is mounted a strip or strips 9, made'of corrugated or otherwise grooved or recessed metal, as zinc, and on the lower side of the Vertical Wire S there is a similar corrugated strip l0. Other lateral corrugated or grooved strips ll ll may be attached to the bottom of the wire S or mounted on rods l2 connected therewith. The rack' or frame should be about ten inches long and five inches wide, one or the other of these dimen sions being common to most photographic plates. By placing the plates 13 so that they tit between the grooves or corrugations of strip 9 and rest upon the bottom strip l0, as shown in Fig. 1, they are securelyheld in the bath into which water may be turned through pipe 2 to wash them. If the plates are of a larger size, they may be placed lengthwise in the vessel, resting upon the grooves orstrips ll ll at the bottom and fitting in the end grooves of strips 7, as shown in Fig. 3.

It will be observed that in using the apparatus described the rack is so constructed and situated that the plates may be put in and taken out freely without coming in contact with anything which would scrape or mar their sensitized surface. The rack is cheap, durable, and efiicient.

What we claim as our invention is l. A rack for holding photographic negatives in a washing and fixing tank, said rack consisting of a horizontal rod or wire shaped to follow the contourof a cross-section of the tank, and a vertical rod or wire shaped to follow the contour of a vertical section of the tank, said rods or wires being joined and each carrying a series of grooved'strips, substantially as and for the purposes described.

2. A rack for holding photographic negatives in a washing and iixing tank, said rack consisting of a horizontal wire or rod shaped to follow the contourof a cross-section of the tank, a vertical rod or wire fastened to said horizontal wire and shaped to follow a vertical section of said tank, and a series of lateral rods or wires attached to the lower side of said vertical rod or wire, said rods or wires carrying a series of grooved strips, substantially as and for the purposes described.

3. A mok for holding photographic negatives in a washing and xiug tank, Said rack Consisting of a plurality of Corrugated or gl'ooved strips 0f metal suitably mounted and supported, one series of said strips being situated adjacent to the bottom of the said tank, and the remainder of said strips being a1- langedadjaoent t0 the nnelfaoes of the sides 0f the tank, substantially as and for the purposes described.
